Get

Looks up the value for a key.

Module: Std::HashMap

Signature

func Get(self, key: int) -> *opaque;

Parameters

Name	Type	Description
key	int	The key to look up.

Returns

*opaque — the value stored for key, or null if the key is not present.

Description

Returns the pointer previously stored with Set.

TIP

Because a stored value may itself be null, a null return is ambiguous. Use Contains when you need to distinguish "absent" from "present but null".

Example

import Std::HashMap::*;

let value = map.Get(42);
if value != null {
    // use value
}
